    How do I wire a Honeywell RTH6350D thermostat to my Bryant fb4anf024 heat pump?
    This is the second thermostat I'm installing, which is sort of the heart of the problem. I installed the first one (a Rite Temp) about 18 months ago with a lot less trouble. Of course, I removed an older thermostat, so I was able to label the wires properly, etc.

    But suddenly the display on the Rite Temp started going south and losing digits / lines. I was able to exchange it for a Honeywell RTH6350D at Home Depot, and now my problems are getting worse.

    When I pulled the faceplate for the new thermostat, the old labels had gone gummy, and some of them fell off. Now I'm at a total loss as to which wires went with what.

    I have the following wires going to the Bryant:

    White
    Blue
    Orange
    Brown (T)
    Yellow (Y)
    Red
    Black (E)
    Green (G)

    My old thermostat had the following terminals:

    W1
    C
    G
    E
    R
    X
    Y
    T
    O

    The Honeywell has the following hookups:
    L
    E
    Aux
    G
    O/B
    Y
    R
    Rc

    I understand that Y goes to the compressor, G to the blower fan, R is the hot 24V AC line, and W is usually heat.

    When I hook it up with Y to Y, G to G, R to R and W to "Aux" I get the fan to turn on, but I only get heat from the registers.

    It's hot, and I have shoulder surgery tomorrow. I'm dreading the prospect of suffering for the next several weeks in sweltering heat after trying to fix this at the last second. Help :-(
